Pydev shows unresolved import, but script runs?

Question

I am using PyDev.

I am trying to organise my project classes into packages.

e.g. In a folder I have a module at /libraries/fund_price_library.py

In another file in my project, I try to import using:

from libraries.fund_price_library import FundPriceLibrary as fpl

PyDev underlines "FundPriceLibrary as fpl" in red, marking it with this error:

unresolved import fpl

However, my script works perfectly fine, so I believe that I am doing the import correctly.

I have lots of similar errors all over my project, and it looks messy. However, my python code works, so I assume I am importing correctly.

How do I suppress these errors?

Answer 1

This question might hold the solution to your problem.

In the properties for your pydev project, there's a pane called "PyDev - PYTHONPATH", with a sub-pane called "External Libraries". You can add source folders (any folder that has an init.py) to the path using that pane. Your project code will then be able to import modules from those source folders.

It might just be that PyDev doesn't know where to find the files.

Answer 2

I had the same issue. Solution is (I have Eclipse 4.6 w/ Pydev 5.6):

Project > Properties > PyDev - PYTHONPATH > tab Source Folders

Do this: Add source folder (button) and add your (current) source dir, in my case it was src subdir so new item apears in the window : /${PROJECT_DIR_NAME}/src

So now I have this there:

/${PROJECT_DIR_NAME}
/${PROJECT_DIR_NAME}/src

and my PyDev is happy now :)
